Abstract
A heterogeneous precipitates have been as ion carriers for the
preparation ofNa (1) selective membrane sensor. The electrodes give nearnemstian
responses in linear concentration range of IM to 1 \ 1 0 with
detection limitsoftheorderof 10'‘M . The stable potentiometric signals are
obtained with in a short time period of 3 minutes. The elTect of pH, and the
elTect of medium have been studied found to give a better response.
Selectively coefficient values (log ) have been evaluated using
fixed interference method. I'he sensors have also been as an indicator
electrode in commerciallv available products.
